The amplifier offsets the input current using a feedback reference capacitor, and produces an output voltage inversely proportional to the valu... |
https://en.wikipedia.org/wiki/VisSim | VisSim is a visual block diagram program for simulation of dynamical systems and model-based design of embedded systems, with its own visual language. It is developed by Visual Solutions of Westford, Massachusetts. Visual Solutions was acquired by Altair in August 2014 and its products have been rebranded as Altair Emb... |
https://en.wikipedia.org/wiki/Probability%20current | In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically, if one thinks of probability as a heterogeneous fluid, then the probability current is the rate of flow of this fluid. It is a real vector that changes with spac... |
https://en.wikipedia.org/wiki/Aortic%20arch | The aortic arch, arch of the aorta, or transverse aortic arch () is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea.
Structure
The aorta begins at the level of the upper border of the second/third sternocostal articulati... |
https://en.wikipedia.org/wiki/Space%20blanket | A space blanket (also known as a Mylar blanket, emergency blanket, first aid blanket, safety blanket, thermal blanket, weather blanket, heat sheet, foil blanket, or shock blanket) is an especially low-weight, low-bulk blanket made of heat-reflective, thin, plastic sheeting. They are used on the exterior surfaces of sp... |
https://en.wikipedia.org/wiki/Le%20Chat | Le Chat (Le Cat in English-language editions) is a Belgian comic strip, created by Philippe Geluck. Foremost published daily in the newspaper Le Soir from March 22, 1983, until March 23, 2013, it is since issued directly as complete albums.

https://en.wikipedia.org/wiki/Domestic%20pigeon | The domestic pigeon (Columba livia domestica or Columba livia forma domestica) is a pigeon subspecies that was derived from the rock dove (also called the rock pigeon). The rock pigeon is the world's oldest domesticated bird. Mesopotamian cuneiform tablets mention the domestication of pigeons more than 5,000 years ago,... |
https://en.wikipedia.org/wiki/Hybrid%20automatic%20repeat%20request | Hybrid automatic repeat request (hybrid ARQ or HARQ) is a combination of high-rate forward error correction (FEC) and automatic repeat request (ARQ) error-control. In standard ARQ, redundant bits are added to data to be transmitted using an error-detecting (ED) code such as a cyclic redundancy check (CRC). Receivers de... |
https://en.wikipedia.org/wiki/Punctured%20code | In coding theory, puncturing is the process of removing some of the parity bits after encoding with an error-correction code. This has the same effect as encoding with an error-correction code with a higher rate, or less redundancy. However, with puncturing the same decoder can be used regardless of how many bits hav... |
https://en.wikipedia.org/wiki/Basel%20Institute%20for%20Immunology | The Basel Institute for Immunology (BII) was founded in 1969 as a basic research institute in immunology located at 487 Grenzacherstrasse, Basel, Switzerland on the Rhine River down the street from the main Hoffmann-La Roche campus near the Swiss-German border. The institute opened its doors in 1971.

https://en.wikipedia.org/wiki/Field%20stain | Field stain is a histological method for staining of blood smears. It is used for staining thick blood films in order to discover malarial parasites. Field's stain is a version of a Romanowsky stain, used for rapid processing of the specimens.
Field's stain consists of two parts - Field's stain A is methylene blue an... |
https://en.wikipedia.org/wiki/Radio%20transmitter%20design | A radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. Radio waves are electromagnetic waves with frequencies between about 30 Hz and 300 GHz. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by th... |
